Thebbject of rnywinvention is to provide a dra t rigging'ofisimple construct on and effitent operation. In the drawings forming a part of this specification, Figure l is a side elevation,

' partly in central vertical longitudinal section, of a draft rigging embodying my invention. Fig.v 2 is a horizontal section, partly in plan view,.the section being taken onthe line 2'2 of Fig. 1. Fig. 3 is a cross section taken on line 3+3, of Fig. 1. In

Figs. 1, 2 and 3, the draft rigging is shown in normal position. Fig. 4 is a horizontal section, partly in plan view, showing theposition of the parts when in full buff. 5 is a detail showing in perspective the ward end of one of the limbs of the draft yoke. I Referring to theldraw'ings, the numerals 66 indicate draft members or parts of the car frame to which the draft rigging is applied. The stop members 7-7 are secured to the inner faces of the draft members, the said stop members being each provided with inwardly projecting portions forming the upper and lower front stop-shoulders 8-8, upper and lower rear stop-shoulders 9-.9,

Fig.

upper and lower rear limiting stops 10-10,

limiting stops forwardly provided with upper and lower yoke stopshoulders 1212. A draft yoke 13 is mount--- ed in horizontal position between the draft members, one limb 14 thereof being re ceived between the upper and lower stopshoulders in one casting, and the other limb 15 thereof being received betw'eenthe upperand lower shoulders in the other stop cast" ing. Each limb of the yoke is provided near its forward end with shoulders 16-16, which j are preferably oppositely arranged,- one on the upper edge and one on the lower edge of county of Cook and State of Illinois, "h ve-invented a certain new and I g e I and exact description, reference being had-to the accompanying,

ed to engage against thle yoke stop. shoulders I 12 .on rearward "ovement of the; draw-bar.

At their'forward ends, th limbs of the yoke are each provided withkaar ansverse slot 1}, the said slots being alined VilllhvtllEtIfilllS- verse .slot 18 through the;draw -b ar 35, the said slots being adapted for the passage of, the coupler -key=19. The cbupler-key-is re-' ceived at its ends inslots 20 20 in. adjacent portions of the-draft mem slots being'longitudinally extended to per mit forward and rearward mit the rearward travel of-the key" 19 therein on rearward movement of the dfraw-ban Front and rear followers 21 and 2:2, respectively, are mounted between the stop'memhers, the said followers being providedwith in-turned lugs 237-23.

the inner springs be'n gseated at with which the followers are provided. .'A tie-plate 29,;re-

.- movably secured to the draft members, preferably by means of the bolts 30-30, is adapt ed to support the compression resisting parts of the draft riggingin position between the draft members. In preferable construction, the draft yoke is rearw'ardlyprovided with a filler block 31 adapted to engage against the rear face of the rear follower 22. The front follower'2l is provided in preferable construction with a forwardly extended portion' 33 passing between the inwardly projecting portions 34-34= of the stop'members," the said inwardly projectingportions forming the front stop-shoulders 8Qand'the yoke stopshoulders 12.

thereon, and the, engagement of the shoulders 16 of the draft yoke against the yoke stop-shoulders 12 with which the stop members are provided. Thus in bufiing action of the draft rigging, the rear follower is held against rearward movement not only by the Y movement of the draw-bar, the coupler-key has free rearward movement in the slots 1? in the draft yoke and in the adjacent slots in the draft members, the draw-bar forcing the front follower rearwardly, compressing the springs against the rear follower, the rear follower being held against rearward movement by the draft yoke through the engagement of its shoulder 16 against the yoke stop-shoulders 12 and also by the rear stopshoulders 9.

On full compression of the parts of the draft rigging in buifing acti on;',-.as illustrated in Fig. 4 of the drawings, the front follower is in engagement against the front limiting stop-shoulders, the shoulders of the draft yoke are in engagement against the yoke stop-shoulders near the forward ends of the stop'members, and the rear follower is in engagement against the rear stop-shoulders and the rear end of the yoke, thus distributing shocks in excess of the capacity of the compression resisting members to three points in the length of each stop 'member.

In a draft rigging for railway cars, the combination with stopmembers having upper and lower front stop shoulders for a front follower and providedalso with separate yoke stop shoulders located in front of the follower stop shoulders, of followers, shock absorbing mechanism intermediate the followers, and a horizontal yoke slidably mounted between said front stop shoulders, said horizontal yoke having upwardly and downwardly extending shoulders near the front end thereof arranged to engage said yoke stop shoulders in bufiing.
